Important – Water Jacket Cover Gasket

This product is the water jacket cover gasket, sometimes searched for as a cylinder head cover / water jacket gasket.

Please make sure this is the gasket you require before ordering.

Important – Please Check Compatibility

Please do not order by horsepower or appearance alone.

Johnson and Evinrude produced different engine configurations across these years.

Before purchasing, please check:

Engine horsepower
Exact engine model
Model year
Engine model/serial number
Existing gasket
Original OMC part number

If the gasket looks the same as yours, this does not always mean it is the correct gasket for your outboard.

If you are unsure, please send us your engine model number before purchasing and our technical team will be happy to check compatibility.
